Original application filed May 4, 1911, Serial No. 625,077. Divided and this application filed August 13, 1912. Serial No. 714,804.

To all whom it may concern:

Be it known that we, Josnr WOLTER, a subject of the Queen of the Netherlands, residing at Rorschach, Switzerland, and AUcUsr BELZ, a citizen of the Republic of Switzerland, residing at Untergoldach, Switzerland, have invented certain new and useful Improvements in Devices for Cutting Embroidery; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification, being a division of our application for'United Stat-es atent, filed May 1, 1911, Serial No. 625,0 7, patented August 12, 1913, No. 1,069,837.

This invention relates to a device for cutting embroidery and the object of this invention is to provide a device by which embroidery of any thickness can be cut out in a short time without being damaged.

In the accompanying drawings constructions according to this invention are illustrated by way of examples.

In the said drawing, Figure 1 is a side view of a first example, Fig. 2 a plan of a second example, Fig. 3 a side view of the same, Figs. 4: to 6 demonstrate the working of the same. 7

Referring to Fig. 1, 2 designates the plate for the fabric, which plate is guided in vertical direction. The shaft 1 of the knife carrier 5 is mounted in the box 3 of the support 1 and secured in position by means of a screw 4. To the knife carrier is secured by means of a clamping plate 7 and screws 8, 9 the knife 10. A finger 12 is secured to the shaft 4. A guide-box 40 is mounted on the support 1 by means ofbracket ll. A shaft 42 to which the plate 2 is connected, is mounted in the guide-box 40. A spring 26 presses the plate toward the knife. The distance of the knife 10 from the plate 2 in the latters topmost position is smaller than the thickness of the unembroidered parts of the fabric. If such a part passes below the finger 12, the plate 2 becomes lowered so much, that the fabric can pass under the knife without being cut.

As soon as the embroidery touches the knife, it becomes out along its edge and separated from the unembroidered parts, whereupon it passes above the knife.

In the example shown in Figs. 2 to 6 the shaft 4 of the knife carrier 5 inside of the support is secured by a screw 4. The finger 12 is mounted on a screw 12 which is connected to the support 32. A shaft 31 is fixed to the support 32 by screws and holds a bearing 33. A spring 34 fastened by a screw 35 to a projecting part 36 of the support 32, presses against a wing 37 of the bearing 33 so that the latter is pressed against the finger 12. For this purpose the bearing 33 is provided with a projection 38 and the finger 12 with a projection 39.

The unembroidered parts of the fabric are moved over the finger 12 in the direction of the arrows, shown in Fig. 5, and pass between the knife 10 and the bearing 33. The spring 34 presses the projection 38 of the bearing 33 against the projection 39 on the finger 12. In this position the bearing gets so near to the knife 10, that only the unembroidered parts can pass freely. 'As soon as an unembroidered edge touches the knife Fig. 6, it is caught by the latter and separated from the background, which passes below the knife 10 and the knife carrier while the embroidery passes above the knife carrier.

We claim:

1. In a device for cutting embroidery along an embroidery-edge, a stationary knife, means to support the fabric parallel to the edge of the knife and acting as counter-part to cooperate with the knife, and automatically adjustable means to bring the knife into action as soon as the latter touches the embroidery edge.

2. In a device for cutting embroidery along an embroidery-edge, a support, a bearing carried by said support, a stationary knife, means tending to move said bearing against the edge of the knife, and means arresting the bearing before it touches the edge of the knife.

, 3. In a device for cutting embroidery along an embroidery-edge, a support, a bearing carried by said support, a stationary knife, means fixed t0 the support, and tending to move the bearing toward the cutting edge of the knife, and a finger fixed on as our invention, We have signed our names the support sold finger belng DlOVldGC]. wlth 1n presence of two subscrlblng wltnesses. a progectlon stnkmg agalnst 2:, correspond- J OSEF WOLTER.
